FREDERICK NERGER, OF CHICAGO, ILLINOIS.

RUBBER HEEL.

Specification of Letters Patent.

Patented Jan. 17, 1922.

Application filed August 31, 1921. Serial No. 497,135.

To all whom it may concern:

Be it known that I, FREDERICK NERGER, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented new and useful Improvements in Rubber Heels, of which the following isa full, clear, concise, and exact description, reference being had to the accompanying drawing, forming a part of this s ecification.

Hy invention relates to improvements in rubber heels. 7

One of the objects of my invention is to provide an improved rubber heel, which will insure a tight engagement between the edge of the heel and the adjacent part of the shoe.

A further object of my invention is to provide a rubber heel which will be durable and efiicient in use and cheap to manufacture.

Further objects will appear from the detailed description to follow appended claims' In the drawings in which an embodiment of my invention is shown Figure 1 is a perspective View of a rubber heel; V

Fig. 2 is a section on the line 22 of Fig. 1;

'Fig. 3 is a section on the line 33 of F l F at is a vertical sectional view showing the heel in position to be attached; and

Fig. 5 is a bottom plan view of the heel in position on the shoe.

This heel is in the nature of an improvement of the heel shown in my Patent No. 1316,9643. The present invention insures a more uniform edge tightness completely around the edge of the heel than has heretofore been secured.

and from the The heel 10 is shaped as a part of a cylinder, the upper face of the heel having a circular cylindrical surface, the axis of which extends from front to rear, all the vertical transverse sections forming arcuate intersections with said surface, all vertical fore and aft sections forming rectilinear parallel intersections with the surface, the outline of the heel being shaped to form the outline of the adjacent portion of the shoe.

In addition to this, in order to insure uniform tightness at the edge all around, I turn up the extreme front and rear edges as indicated at 11 and 12 respectively, so that these portions of the heel come in contact with the shoe before the central portion of the heel does, as shown in Fig. 4, so that the entire edge portion or circumference of the heel is pressed tightly against theshoe when the nailslS'are driven in.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent of the United States is:

A rubber heel-having its upper face a circular cylindrical surface, the axis of which 'heel being shaped to conform to the outline of the adjacent portion of the shoe, the front and rear edges of said heel being turned upwardly to insure a uniform edge tightness all the way around the heel when the heel is secured to the shoe.

In witness whereof, I have hereunto subscribed my name.

FR-EDERICK NERGER.
